Nice work on rendering your male figure standing attitude, Jason, that's a very technically good job.
Again, I really feel that it's a teeny bit too rigid and stiff there. Why don't you please liven yourself up with your line quality, by working out with 156 minutes of 30 second attitudes??? (156 x 60/30=9360/30=312 ruff poses/5 days a week=62 crude poses a day, in a week, all flipped horizontally and/or vertically, or normal, thru the special tools for our members on Line of Action; Or you can take a screenshot of each pose, so that you would flip them yourself)
The reason why you could and should go with this extremely and totally beneficlal critique is so, that you would be able to tap into your perceptions of the figures' edges, and the right side of the brain, even if it's through the quicker gestures. And that applies to your amazing head drawings. For more info, I encourage you look up for the PDFs or the books, or ebooks of the Loomis and Reilly figure drawing and head sketching books.
So, cheers, and hat's off to you.
